Color Converter
Frequently Asked Questions
Do colors have commonly recognized names?
The CSS specification defines about 140 named colors (such as crimson, teal, coral, rebeccapurple, transparent). You can enter any of them, and the tool will automatically convert it into precise HEX, RGB, and HSL values.
How do I check text and background contrast for a website?
Contrast between text and background is an accessibility requirement (WCAG): colors too close in lightness are hard to read. When choosing a pair, check the lightness difference — the third value (L) in HSL.
Does the tool support transparency (alpha channel)?
Yes. When entering colors with transparency (such as 8-digit HEX #8f5aff80, rgba(143, 90, 255, 0.5), or hsla(260, 100%, 68%, 0.5)), the tool calculates exact HEXA, RGBA, and HSLA values. The standard HEX, RGB, and HSL fields show the base color without transparency.
What do the letters in HSL mean?
H is Hue, defining the color on a wheel from 0 to 360 degrees. S is Saturation in percent. L is Lightness in percent: 0% gives black, 100% gives white.
Are CMYK, RAL, or Pantone formats supported?
No. The tool is designed for web styling and screens, converting between HEX, RGB, and HSL. Print models (CMYK) and paint catalog standards (RAL, Pantone) are not supported.
Does the same HEX code produce the same color across devices?
The code is identical, but display calibration and color profiles vary — the same HEX value can appear slightly warmer or cooler on different screens.
Does the tool generate a full palette automatically?
The tool converts a single color into its equivalent representations for CSS. To extract an exact color from an image, use the image color picker.
Convert colors between HEX, RGB, HSL, and CSS color names. The tool supports transparency (HEXA, RGBA, HSLA) and lets you instantly copy styles for CSS. Enter the value in the "Color" field and press "Convert".
Ways of writing a color
| Format | Example | Where it is used |
|---|---|---|
| HEX | #3A7BD5 | CSS, website layout |
| RGB | rgb(58, 123, 213) | CSS, programming, working with transparency (RGBA) |
| HSL | hsl(214, 64%, 53%) | Picking shades of one hue by lightness and saturation (HSLA) |
HEX, RGB and HSL describe screen colors and convert into each other while preserving the original color channels. For colors with an alpha channel (transparency), the tool calculates exact HEXA, RGBA, and HSLA values. The standard HEX, RGB, and HSL fields show the base color with transparency omitted.
How to pick a color combination
The color entered is a starting point, not a ready-made palette. The classic approach to combinations is built on the color wheel:
- Monochromatic combination – one hue, different lightness and saturation. In HSL it is enough to change just the second and third values, leaving the first one (the hue) unchanged.
- Contrasting combination – colors from opposite sides of the wheel, for accents and high visibility.
- Analogous combination – colors next to each other on the wheel, for a calm, cohesive palette.

If the starting color needs to be picked up from a finished image or a screenshot rather than typed in by hand, use the color picker – it returns HEX, RGB and HSL right when a pixel is clicked.
